120/20=5
Answer:
given below
Step-by-step explanation:
let the number of gloves be y
then number of masks is y + 8
therefore a equation can be formed:
18(y) + 24(y + 8) = $612
18y+24y+192=612
42y=420
y=$10
each glove cost $10
therefore each masks cost $18
For this one you can use 3/8 + 3/8 since 3+3 is equals to 6 and the 8 stays as it is.
I hope this helps.
YOU'RE WELCOME :D
